Portable Variable Frequency Resonant Test System Lightweight AC Hipot Test Equipment for On Site Cable, GIS and Substation Testing

The Portable Variable Frequency Resonant Test System is designed for power utilities, engineering contractors and electrical testing companies that require flexible on-site high-voltage testing.

The modular design allows the complete system to be transported and assembled at substations, cable sites and power plants.

By using frequency conversion resonance technology, the system can reduce the required power source capacity for suitable capacitive test loads.

Q: Is every series resonant system portable?
A: No. Portability depends on the system voltage, capacity and reactor size. Larger systems may require modular transportation.

Q: Can the equipment operate with different site power supplies?
A: Depending on the configuration, systems can be designed for common single-phase or three-phase power inputs.
